HUMIDIFIER.

v Specification of Letters Patent. 'Patnted @m3, 1918,

Application filed April 29,1318. Serial No. 231,566.

To all whom t may concern.' y

Be it known that I, HERBERTP. IIEIss-, a citizen of the United States, residing at Chicago, in the county of Cook and State ofI Illinois, have-invented certain new'and useful Improvements in Humidifiers, of which the following is a specification.

My invention One of the objects of my invention is to provide a device, for thel purpose described, which may be relatively smallfor its capacity, simple in form and cheap of construction. i

vide Aa relatively thin water receptacle, and fabric having'l considerable capillarity, whereby to raise the water to the uppersurface of the receptacle to expose a' relatively large surface area of moisture directly to the air.' v

Otherand further objects of my invention will become readily apparent, to persons skilled in the art, from a consideration of the following description whentaken in conjunction with the drawings, wherein Figure 1 is a perspective view of the humidifier. s

Fig. 2 is a, plan view.

Fig. 3 iqsja transverse section taken on line' 3- 3 of Fig. 2.

In all the views the same reference characters are ,employed to indicate similar The water receptacle 5 is arelatively thin .and tall metal can, having a flat even front and corrugated rear wall. 40

The rear wall 6 'may have a plurality-of angular., spaced apart lateral project-ions 7, as" many as de# sired, in accordance with the capacity of the device, which are separated properly to be contained between adjacent coils of a heat-- ingradiator.

To the inner surfaces of these projections, atl their apices, are attachedcurved supporting-wires 8A andl 9. These wires Vhook over the coils of the radiator and serve assupports for the humidifier.

A .cover 1.0, for the receptacle, has a downturned marginal edge 11, which overliesthe.

jection 7, through which vaponfrom the heated water within' the receptacle may escape. The top is perforated witha series of relatively vnarrow-slots, 1li-'14, relatively closel together and another .series vof slots l5-15, separated .from the first series by a' longer space. A relatively thin, long stripv of fabric or wick 16, is intended to 'extend from the bottom of the receptacle. 5 up to the cover- 10. It' is then threadedalternately through the slots 14 and 15, leaving relatively large 'surfaces 18-18 exposed upon the -upper surface of 'the' cover top.

vThe leg 19, of the fabric, extends at one end near the'bottomand the leg 20 extends near the bottom 4at the' other end of the recep' tacle, so that these two`legs of the fabric are immersed in the water vcontained ,in the .receptacle and by their capillary e'ect, they carry the water up to the exposed'isurfaces' 18 thatoverlie the cover 10 of the'jh'umidifier. This always maintains the surfaces'1'8 moist for contact with the relatively ldry air thatis being, orhas been'heated, by the radiator. l

If the legs'19 and 20 are not sufficient'for the purpose, that is to say,"when the humidifier lis relatively longl and :thecapillary effect of the legs 19 and 2O isnot capable of sup# plying the entire surfaces 18, an .auxiliary wick or'fabric may .be dependedf-rom the cover, consisting of the -legs 21 and 22.- The ln-idportion of this auxiliary wickl may be threaded under the-wick 16 inthe inidpoition ofthe humidifier, as shown' in Fig.. 4. I have -indicated this auxiliary 'wick or capillary 'fabric16 .v As many 'of these auxiliary wicks 16.l 'may b'eA employed, as desired, and. attached tothe cover 10 in the.l manner shown,v at as inany intermediate points a's-'may be required.

. @The immidiaeir my be fined with Water 'through either of the` holes 12 or'll, and the progress lof the filling operation may be observed. through the hole into which water extent to which the receptacle is filled, can be readily'ascertained during the filling operation.; v i .Having described my invention, what I claim'is:- l v A humidifier comprising a relatively thin, tall receptacle having'a plurality of angular, lateral projections in its rear wall; a cover having a marginal edge. encompassing the top lnarginal edge of the receptacle, having ing near-to the bottom of the receptacle at spaced-almrt,4 transyersely-extending Slots each end of the coer and providing large at- 'frequent intervals in its wall and perfoexposed surfaces on top of the cover. 10 rat-ions for filling'7 overlying said angular In testimony whereof I hereunto set my projections, in combination with a capillary hand.

wick or strip of porous fabric threadedI through said slots, having portions eXtendi HERBERT P. HEISS.
